1 Claim.

This invention relates to improvement in bombs. It is an object of theinvention to provide a bomb including an outer cylindrical shell havingone closed conical extremity to the bore of which one end of acylindrical inner casing is secured, thereby forming an annular spacebetween the shell and the inner casing to receive a large number ofprojectiles while an explosive charge is housed within the casing.

Another object of the invention is to provide such a bomb wherein oneend of the inner casing is secured to the bore of the shell and isclosed by the conical extremity of the latter, and a cap closes theopposite end of the casing and is provided with an annular projectionwhich retains a flange in position over the adjacent end of the shell toclose the annular space wherein the projectiles are loaded. Moreover thecap and flange arrangement is such that the latter holds the innercasing concentric in the shell and thus reinforces the attachment of theother extremity of the inner case to the conical end of the shell.

A further object of the invention is to provide a bomb which is cheapand simple to manufacture, and easy to load and charge.

Having thus stated some of the objects of the invention I will nowproceed to describe the invention in detail with the aid of theaccompanying drawing, in which the figure illustrates a longitudinalsection of the invention.

Referring to the drawing, I designates a cylindrical inner casing whichis filled with an explosive charge I0, and 2 is an outer cylindricalshell having a closed conical extremity to the bore of which oneextremity of the said inner casing I is suitably secured as by weldingor in any other preferred manner. To insure a better contact between thebore of the shell and the end of the inner casing the latter may beinwardly tapered to correspond with the inclination of the conical endof the bore of the shell which is substantially parallel to the outerperiphery. Extending, preferably axially, through the closed conicalextremity 3 of the outer shell 2 is a spindle 4 on a conventional fusedevice 5 which is provided within the adjacent end of the inner casing Ito detonate the charge I0. Loaded in the annular space confined betweenthe inner casing I and the outer shell 2 are projectiles which in thepresent instance are shown partly as slugs or pellets l I of irregularshape and partly as fiat pieces of metal Ila. lying one on top of theother, though obviously either the slugs or the flat pieces of metal maybe used to the exclusion of the other if preferred.

The opposite extremity of the shell 2 is closed by an annular flange 6having a downturned outer margin which fits over the outer periphery ofthe said shell. The adjacent end of the inner casing I is internallythreaded to receive a cap I which has an annular projection Ia thatextends over the inner portion of the flange 6 and retains it inposition and also helps to maintain the casing and shell concentric orcoaxial since the bore of the flange 6 lies immediately adjacent theouter periphery of the inner casing. 3 denotes a countersunk multi-sidedwrench receiving opening in the outer side of the cap I for screwing thelatter into the casing, and 9 are wings for retaining the bombsubstantially in vertical alignment during its fall.

While in the foregoing the preferred embodiment of the invention hasbeen described and shown, it is understood that alterations andmodifications may be made therein provided the said alterations andmodifications fall within the scope of the appended claim.

What I claim is:

A bomb including a cylindrical inner casing having an explosive chargetherein, a cylindrical shell coaxial therewith spaced around the casing,said shell terminating at one extremity in a substantially conicalclosed end through which a fuse mechanism projects, the bore of theshell extending into said conical closed end and the thickness of theshell being uniform throughout its length, one end of the inner casingbeing annularly secured to the bore of the shell toward its conical endwhereby a projectile space is defined between the casing and shell, anannular flange on the opposite end of the. shell having a downturnedmargin extending around the periphery of the latter, the bore of theflange terminating immediately adjacent said casing, the free end of thecasing being internally threaded, a cap in threaded engagementtherewith, and a projection on said cap retaining said flange inposition.
